Research offers means to detoxify mycotoxin-contaminated grain intended for ethanol, animal feed

Using barley as the raw material for ethanol production results in an additional product – dried grains for animal feed. But the presence of a fungal pathogen sometimes found in barley can result in a lethal toxin, called mycotoxin, in the animal feed. Now, Virginia Tech and Agricultural Research Service, USDA researchers have shown that newly developed transgenic yeast used during fermentation will help modify the mycotoxin in the animal feed product to a less toxic form. The research is published online in the September issue of Biotechnology for Biofuels.
